The conjugate acid of ch3nh2 is ch3nh3+<span>.
</span>For example methylamine in water chemical reaction:
CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻(aq).
According
to Bronsted-Lowry theory acid are donor of protons and bases
are acceptors of protons (the hydrogen cation or H⁺). Methylamine (CH₃NH₂) is Bronsted base and it can accept proton and
become conjugate acid (CH₃NH₃⁺).
Answer : The correct option is, 
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:

where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:

where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Fahrenheit is, -10
Now we have to determine the temperature in degree Celsius.



Now we have to determine the temperature in Kelvin.



Therefore, the temperature in degree Celsius and Kelvin are, 
Low temperature in water and an increase in salinity.
The type of reaction in above reaction is refered to as a disproportionation reaction .It sometimes used to describe desymmetrizing reaction.in the equation above compounds of intermediate oxidation state are converted to two different compound, that is Clo3 ions and 2cl-
